In January 2026, there were 118,907 vehicles registered with the DC DMV at 89,871 residential addresses, according to data provided in a recent FOIA request.

Keep in mind that this does not include any vehicles that are owned by DC residents, but registered in another state. This also doesn’t include vehicles registered at non-residential addresses.

The DC DMV website says there are 310,000 total vehicles registered in DC.

Let’s ignore the fact that some of these vehicles are likely construction vehicles and other large trucks. If we add up the number of 9’x18’ parking spaces required for these 310,000 vehicles, we get a total area of 1.8 square miles (162 sqft * 310,000 vehicles * 3.58701e-8 sqmi/sqft). If you parked all of these vehicles bumper to bumper, they would cover Capitol Hill.

This write up will analyze the distribution of vehicle ownership in the data set DMV provided.

According to this FOIA’d data, here is the number of vehicles registered in each ANC Single Member District (SMD):

Here is the number of vehicles registered as a percentage of the number of households in the tract in 2020.

We can correlate median household income in each tract in the 2019-2023 5-year American Community Survey with our “# vehicles / # households” statistic. When we do this, we find that every $25,000 increase in tract median income is associated with an increase of 7 additional cars per household.

There are 43,919 registered vehicles within 800 meters of a metro station in DC according to this data set. That is 37% of the total number of vehicles.
